I told that not only you but also other girls should learn about Bitcoin and Blockchain technology. She told me that she will share her experience about Bitcoin with her college friends. I am now much happy by sharing with my younger sister about Bitcoin and will be more happy if she share information and teach other friends.
Bitcoin was created not only for men, but the creation of bitcoin is definitely for all mankind in this world, who are capable of buying or investing. Because until now I have never heard of and found no news containing the prohibition of buying bitcoins for women. So if there are women who are as interested in bitcoin as your sister, they are women who are very smart and have good minds. But women who invest in bitcoin are still very few. Because if I look at the women around where I live, almost 95% don't know about bitcoin, and 5% of women who know also seem less interested in bitcoin.
maybe in the country where I live it won't be much different either, you could say it's still a minority.
Maybe because of that, what makes a woman who invests in bitcoin is still considered foreign and not prominent.
But you have to be wary of your younger sibling who is starting to spread these bitcoins, because even though bitcoin is indeed a very high quality investment asset, still if you still don't know about the science, the results will definitely not be good. And what's more, your sister spreads it to her friends, I think it will be quite risky.
